Understanding FlightInfoEx and event sequence

Hi team,

I’m new in the flight tracking world and i’ve so much questions that i wish you could help me to answer.

  • From my understanding, we can find a flight from FlightInfoEx maximum 3 days before departure. Can you explain why ? Flights are scheduled by airlines weeks, months, years ago so why we cannot find flight more tha, 3 days before departure ?

  • When subscribing to e_filed and e_change events 3 days before departure and flight schedule changed within the 3 days, do we receive an e_change event before the e_filed event ? Or do we always receive the e_filed event first 1/2 hours before departure and then a e_change event if time has changed ?

Thank you very much guys for your help.
